ELECTRICAL VALVE.

To all whom it may concern:

Be it known that I, HARRY LEWIS, a citizen of the United States, residing at Pittsh,-in the county of Allegheny and State ennsylvania, have inventedcertain new and useful Improvements in Electrical Valves, of which the following is a specification. 7 The present invention relates to improvements in electrically operated valves, designed for valve which isadapted to be used on pipe lines conveying water, gas, air,

the internal pressure of the fluid so carried tending to exert a pressure on the valve head and thus assist in holding same securely on the valve seat, producing a val vs at is secure against leakage. A further feature of the tion", is there being but a comparatively small number of parts to the valve; and the electromagnets operating same being located externally with relation to the valve chamber, and hence not afi'ected by the nature of the fluid ca rried, the mechanism of this form of valve is not easily deranged, and thus makes a valve which IS positive and reliable in operation, andsiinple in construction.

y means of certain will hereinafter be explained, the valve can e regulated, so that any required amount of fluid will pass through it when in a partly closed position. A feature which is very useful invsome situations, as ii iii use of as for instance, where the pile, to he maintained; by

This valve having few working parts within the valve chamber, hardly any obstruction is placed in the path of flow of the fluids passin through it, when the valve is open and de ivering its maximum disc arge.

best modes I have so far devised practical pplication of the princi ples of the invention.

Fig. 3 is a 2 of Fig. 1.

he numeral 1 designates or shell of. the valve, which the outer casin is made of nonmagnetic material, surmounted by a cap 2 also of non-magnetic material. and screwed to the top of the outer shell 1 as shown.

bove the cap 2, is an electron'iagnet 3 of the usual construction; capable of being energized from a source of power through feed wires!) and i0. 'Ihrough the olecfromagnet 3, and valve cap 2 passes a soft iron core 4, being threaded through the lotto-r for purposes of adjustment, and ex tend ug some distance into the valve chamber 5, as; shown in the drawings. l/Vithin the valve Chamber 5 is located the alve head 6, valve stem 7, and the ring 8 through which the valve stem passes, the ring forming a guide for the same, so that the valve head 6 will always some to a perfect seat on the valve seat 11.. lt will be noted that the distanee between the top of the valve stem 7 and the bottom of the iron core 4 is I'Qglllllifit'l by the position of the latter in the head 2, the distance between the two determining the height the valve head 6 will rise ofi its seat 11, as is readily seen. The upper and outer edge 12 of the valve head 6 is of shape shown in order to facilitate the flow of fluid passing through the .valve, when the valve is open. Within the valve passage'lli, is located an adjusting screw 14 which is threaded through the wall of the valve body, and carries a lock nut 16 and a milled head 17. of said screw 14 is to control valve shall remain partly open, the screw 14 mg the aperture 18, thus permitting a'srnall well governed flow of gas or other fluid through the valve. hus be seen that a pilot light can be maintained when the maximum flow of gas is not desired. After the ad'usting screw 14 has been set at any point in height with relation to the under side of the valve head 6, it can be looked in osition by means of lock nut 16. Opening rem the side of passage 13 is a the valve bodv 20, throu h which connection ma be made to outle pipe 21. Also from vs vs chamber 5 e tends duct 22 and extension 23,

cross sectional view on line through which connection may be made with inlet pi e 24.

The ass portion of the valve body is made identical with the upper porti on thereof, there being a cap 27, of non-magnetic material, and electroma et 28 with feed wires 32 and 33; and an iron core 29, screw threaded through cap 27, all similar to the parts 2, 3 and 4, previously described. These parts on the base portion of the valve are to provide a means 0 bringing the valve head 6 to its seat.

By locating the electroma et outside the valve chamber practically a danger of the destructive action of fluids passing throu h the valve is avoided. It is essential that t e windings of the electromagnets be kept separate and apart from any such strong flui s, that would destroy them, and injure the action of the m nets, and with same the posi-- tive action of t e valve. It is also seen that the iron cores being screw-threaded through the caps 2 and 27, obviates the necessity of packing boxes of any character, which is seen to be an additional safeguard against a non-reliable valve.

The operation of the valve in a position other than vertical is as follows: The opening of the valve is effected by energizing the the bottom of the iron core 4. The flow of the fldid: is now complete, passing through 18, 13 and 19,into exit pipe 21.

When -it is necessaryjo close the valve electromagnet 3 is den zed and the opposite magnet 28 is energized and the iron core 29 attracts the end of the valve stem 26 and returns the valve to its seat.

Havin thus full described my invention, what I c aim and esire to secure by Letters Patent is:

In combination a chambered body, open at its ends and havin a lateral inlet and a lateral outlet, togeter with an intervening valve seat, caps of non-magnetic material for the respective ends of the said body, an

eleetromagnet mounted externally on each cap, with its core adjustably protruding through said cap into the chamber of said body, a valve head adapted to cooperate with said seat to control communication between said inlet andsaid outlet, stems projecting from the respective faces of said head and serving as armatures for the respective magnets, and an adjusting screw passing 0bliquely through the valve body and adapted to engage the valve head whereby the valve may be maintained 011: its seat.

In testimony whereof, I hereby aflix my signature, in the presence of two witnesses.
